Fiber Optics, Optical Networking Terms
A continuously variable signal. A mercury thermometer, which gives a variable range temperature readings, is an example of an analog instrument. Opposite of digital.
AJA_Glossary of Wireless, RF and Microwave Terms
The traditional method of transmitting voice signals where the radio wave is based on electrical impulses, which occur when speaking into the phone. Most cellular companies today transmit in analog.
Jensen's Technology Glossary
Almost everything in the world can be described or represented in one of two forms: analog or digital. The principal feature of analog representations is that they are continuous. In contrast, digital representations consist of values measured at discrete intervals.
Digital watches are called digital because they go from one value to the next without displaying all intermediate values. Consequently, they can display only a finite number of times of the day. In contrast, watches with hands are analog, because the hands move continuously around the clock face. As the minute hand goes around, it not only touches the numbers 1 through 12, but also the infinite number of points in between.
Early attempts at building computers used analog techniques, but accuracy and reliability were not good enough. Today, almost all computers are digital.
A description of a continuously variable signal or a circuit or device designed to handle such signals. The opposite is discrete or digital.
Digital Video (DV) & video edit terms / Eng2Eng v1.0 (web compilation)
An electrical signal that is continuously variable.
Information represented electronically as a continuous, varying signal. (See also digital.)
Television and Video Glossary
Refers to systems that represent or encode or transmit information in a manner that is continuously variable, specifically not having to be rounded up or down to certain numeric values or being restricted to discrete pixel positions on a line. An analog picture reproducing system for example might reproduce any shade of red from a dark brown to a light pink while a non-analog system might only have twenty specific shades of browns, reds, and pinks to choose from. NTSC video is analog in the horizontal direction; details can occur anywhere along a scan line. It is not analog in the vertical direction; details that "fall between" two scan lines are lost or show up shifted slightly to fit on one of the scan lines.
Electronic Music Glossary
Data (signal) presented in a non-digital, continuous form.
waveforms, with valleys and ridges, referring to the natural form of sound/audio. To store/playback on a computer, analog data is converted to digital data.
Glossary of Electronic Music Terms
Capable of exhibiting continuous fluctuations. In an analog audio system, fluctuations in voltage correspond in a one-to-one fashion with (that is, are analogous to) the fluctuations in air pressure at the audio input or output. In an analog synthesizer, such parameters as oscillator pitch and LFO speed are typically controlled by analog control voltages rather than by digital data, and the audio signal is also an analog voltage. Compare with digital.
Video Essentials Glossary of Terms
A continuous signal that requires time to make a transition from one level to another. Standard audio and video signals are analog. Both can be digitized. The video in the laserdisc format is analog composite. The audio can be present in both analog and digital forms. Both the audio and video on DVD has been recorded on the disc in the digital domain. The alternate, British spelling of the word analogue is often used in the audio world.
